Preproman, take your time and hope you enjoy the sound. Are you burning in 24/7? Will love to hear your thoughts soon too!
Yes, was chatting with Greed over PMs a few days ago and indeed he is enjoying the Dp-777. He actually prefers Dp-777 over his MSB Analog dac with GS-X MkII and HD800 and now he uses the MSB Analog for his speakers set-up instead.
I am sorry if it is confusing, I have never used the O2 amp with the Eximus dac. The comparison i just posted was between DP-777 through Eximus internal amp and Dp-777 through O2 amp. Previously when I compared Eximus dac and dp-777, it was through the Eximus internal amp and the Dp-777 was clearly better in most departments. I hope it clarifies.
How would you rank the Eximus internal amp, in absolute term?
I used it for the Mad Dogs 3.0 only (I only had balanced headphones, besides the MD) but it was not all that great compared to the SA-31.
Now that more efficient planar headphones are out (hello LCD-X), it might be interesting to see what the DP-1 can do standalone.
There's always the Audio-gd options for an all-in-one, of course.
